New Marsupials from Centred Australia. 



A few long whisker-like hairs on the posterior side of the 

 fore-limb, just above the wrist, the longest measuring about 

 40 mm. 



Mamixue, 8. Two or three young ones apparently produced at 

 one time. 



Dimensions. 



Specimen (a) has two young ones in the pouch. Specimen (/>) 

 has the hinder pair of mamma? very small. Specimen (d) has 

 three young ones in the pouch. The posterior mamma on the 

 right side is wanting. The anterior pair are small. The second 

 pair has an embryo attached on each side. The third mamma 

 on the right side is small, that on the left has an embryo 

 attached. The fourth on the right side is not developed, and 

 that on the left side is small. 



Skull (Plate II., Figs. 1 and 2). Much smaller and more delicate 

 than in P. lagotis. The upper anterior end of the Premaxillary 

 only slightly directed forwards, not so strongly marked as in 

 P. lagotis, and in consequence the tip of the muzzle seen from 

 the side is not so markedly trifid as in P. lagotis. Nasals long 

 and narrow, their greatest breadth going between 4| to 4| times 

 into their length. Interorbital region flat and not conspicuously 

 constricted :* relatively much broader than in P. lagotis. Lachry- 

 mals much as in P. lagotis with a distinct ridge marking off the 

 facial from the orbital surface. 



* In the specimen of which the dimensions are given the intertemporal breadth (11 mm.) 

 is exactly the same as in a skull of Peragale lagotis, the basal length of which is 90 mm.
